I've had this idea in the back of my head for quite a while, but because it's actually a thing now. I guess I should tell you guys.
Beastmaster : A robot with a green-clad outfit riding a specially armoured Fire Raptor, he appears as the final boss of the 3rd chapter. He rides around on his raptor, breathing fire everywhere. After his raptor is killed, he'll enter berserk mode, calling in mark 3 robots and drawing out a sword, he essentially has the same skills of a more advanced Mark 4 sword robot with more resistance.
I hope you guys liked the sketch I made :)
